The IT Division has over 100 virtual machines running on an enterprise VMware based environment. The Infrastructure Group within the Lab’s IT Division has been deploying virtual machines using VMWare in a pilot mode since January 2007
Three primary reasons why we think this makes sense: Energy Savings, space optimization, and increased efficiencies in deployment of new applications.
- Energy savings accrue due the reduced use of physical servers for testing and development environments, which typically have much lower duty cycles, yet consume a significant amount of energy while powered up.
- Increased Efficiency: much quicker response in setting up test and production environments, ability to have virtual machines for product and service evaluations-to perform ‘what if’ scenarios without buying a physical server. It will also reduce costs in acquisition of underutilized single purpose physical servers.
- Space is a critical resource at the lab. By consolidation of physical machines into institutionally provided computer room space using virtualization technology, office space can be reclaimed to support the significant growth in lab employee count.
We have extended use of the VM environment to experienced system administrators who work in the IT Division on behalf of a customer. Because we can restrict the scope to experienced staff, the costs for providing the service can be reduced.
